Jim, You are the one of the best know, if not the best known, of all the contributors to the CBT tape.
Thank you. I found your code extremely helpful on numerous occasions. Both Sam's are truly commendable. You all selflessly worked to serve the industry and the rest of us. "Goodness is greatness . . ." (Mary Baker Eddy) I first met Sam Golob on a consulting gig at CDCSA, the NYC data center, and I met the other Sam at Mount Sinai Hospital. All of you belong in the Who's Who of Mainframe, CBT, and SHARE. Thank you all.
